Dual IM386 Chip amp

Started by Paul Craig. Last reply by Paul Craig Nov 6, 2015. 4 Replies

A while back I posted on the comments about this nasty little op amp that I built. It has 2 IM386N1 chips and it's a 2 stage amp. It was inspired by the Ruby amp.…Continue

Can anyone direct me to plans for a small mini amp? I had a couple but lost them when my computer crashed. Something along the lines of the old Lil' Smokey amps that were housed in cigarette boxes. I…Continue

Came across an old 80 watt PA amp today. Providing it's working, how well will it work for the Electric License Plate guitar I made with the single coil pickup? It has a phono and aux input

Like Paul, I was thinking, fun distortion but I'd like to hear it at a bit more mellow setting to see how the heart of the thing sounds.  It does well at high volume levels... but hard to hear the true voice of the amp with all the noise.  Would love to hear it at a lower, non-distortion volume.  : )

Comment by Paul Craig yesterday

A wood cabinet will soak in some sound waves, but a metal cab will reflect it all back and that can be a problem. It also adds to the unique sound. Might try a soft liner across the back side of the can to try out.

Comment by Paul Craig yesterday

It has a good raw sound to it Dr X. A little too much noise though. Did you use any shielding in the can? Were you playing a guitar with a single coil pickup?

I found this Admiral tube radio at the New Glasgow Flea Market. The first intention was to convert it into a tube guitar amplifier. After much research, this idea was not a good one. So instead, I removed the tubes and old circuit and installed one of my 1/2 watt guitar amp circuits. The original field coil speaker had a torn cone. So it was replaced with a modern one, added an LED light just above the dial face so when the amp is turned on, the dial lights up.
Had the old radio been something of value, I would have restored the insides.
Now it is a nice practice amplifier, which can also be used with an MP3.

It is for sale. PM if interested.

Hello, just joined the group. I got into amp building out of necessity. Had a 10w guitar amp that quit working after 6 months and the board was too bad to fix. I built a Ruby amp out of it. The Ruby is a 1w version of a Fender Champ with a IM386 IC chip that sounds great with the 6 inch speaker. Of course later I found myself wanting more gain, so I made a dual chip version with 2 stage gain. I'll look around and find my schematic to post it later.

Hey Cameron, could be anything really. Capacitor needing replaced, output transformer, or ? Is the radio quiet too? Or is it just when testing with the guitar?
